Some drivers have been complaining to the Iowa Department of Transportation about the current condition, but officials said the changes are not the results of a finished product.

“It doesn't look the best, but when we're done we will have a fresh coat of asphalt on the whole project and we'll also have wet, reflective pavement markings. So, the markings will really pop,” said DOT project engineer Jessie Tibodeau.

Crews have been working since late July to repair cracks between the lanes on the stretch of I-235 between 31st Street in Des Moines to 50th Street in West Des Moines.

So far, the repairs have left behind a bumpy, rutted road and plenty of black stains. It's the asphalt left over from the two-foot-wide patches.

It’s only been seven years since the DOT rebuilt the entire Des Moines freeway system, but maintenance is ongoing.

The project is expected to be completed in October, and it will cost $6 million.
